●● True or False: Direct current reverses direction at regular intervals.
Answer: False
●● For a collection of resistors that are connected in series, which of the
following statements is true? Assume that the resistance of each resistor
is different.
Answer: a) The current through each resistor is the same
b) The equivalent resistance is equal to the sum of the individual
resistances
c) The total voltage across the circuit is equal to the sum of the
individual voltages
d) A,B, and C are true
●● True or False: Kirchhoff's Loop Rule states that the sum of the
potential differences around any closed loop in an electric circuit is
always greater than the current in the circuit.
Answer: False. Kirchhoff's Loop Rule states that the sum of the electric
potential differences (voltages) around any closed loop is zero.
, ●● For a collection of resistors that are connected in parallel, which of
the following statements is true? Assume that the resistance of each
resistor is different.
Answer: The sum of the current through each resistor is equal to the total
current of the circuit
●● True or False: Kirchhoff's Junction Rule states that the sum of the
current entering a junction must equal the sum of the current exiting a
junction.
Answer: True
●● The circuit in Figure 8.T.5 contains two batteries and one resistor
connected in series.
At which point is the current the largest?
Answer: 2 Batteries in Series w/ Resistor Parallel
The current is the same at all of the points
●● The circuit in Figure 8.T.5 contains two batteries and one resistor
connected in series.

Answer: 2 Batteries in Series w/ Resistor Parallel
Point C
